In the test "bronf1 - graph - gursoy_atun_layout_test / gcc-cygwin_4.3.2",
there is an error "execvp: Argument list too long". I understand that
those tests have not run recently, but is there a way around that length
problem? I believe Cygwin has a response file feature that allows longer
command lines. Is this problem important enough to suggest using that
feature? Also, will that platform start to have tests run again?
